a)-6(x-2) = 4r-17
B) 10x +307 - 20) = 13-20
6) (18-19) -(4-720) = -73
г)-3(4-5y)+2(3-6y)=-39
Answer:
d. 3 to the power of 2 multiplied by 1 whole over 4, the whole squared. = 3 to the power of 4 multiplied by 1 squared over 4 squared. = 81 over 16.
Step-by-step explanation:
This is an exercise in PEMDAS, the order of arithmetic operation:
parentheses > exponents > multiplication and division > addition and subtraction.
[(3² × 5⁰)/4]² = [(9 × 1)/4]² = (9/4)² = 81/16
3⁴ × 1²/4² = 81 × 1/16 = 81/16
a. is wrong. 3¹ × 1²/4² = 3 × 1/16 = 3/16
b. is wrong. [(3² × 0)/4]² = [(9 × 0)/4]² = (0/4)² = 0² = 0
c. is wrong. [(3² × 0)/4]² = 0
Commutative because it’s switching the numerals to make an equation
